Hello Nick, it’s been a while, am finally circling back to dialing in the stereo template best for this project. I’m good with editing the FFakeStereoRenderingDevice class in VS 2013, able to package exe and 3d looks quite acceptable with our settings. FYI the defaults for float EyeOffset are channel swapped, left eye data goes to right eye and vice versa, big 3d no no, but moving on. In our project the user picks up a flashlight at the entrance to this cave, which then lives at the bottom of the screen locked to the camera and shines dynamically wherever user navigates and looks. I wish to adjust the convergence point (set screen plane), have through your responses here, but remain unclear which variable controls this. I understand if you change one parameter, you’ll likely need to change another, as the other values aren’t locked, they all work in a system. Thanks for advising.
